This is a note of interest for the "gonnabe" live aboard's. Since installing a new refrigerator and sperate freezer a while back I have been thinking of ways to use the space left vacant by the removal of the old, so called "holdover" freezer space. It's a fairly big space that I had thought to install a drop in 12 vdc refrigerator system for about $1,200, when all said and done.
The problem with boat refrigerator systems are, they are very expensive, require a lot of installation and reconstruction and whatever food product touches the evaporator plate freezes. Added to that they consume about 6 amps DC per hour.
Capt. Mike told me of a system, that in appearance looks like a Coleman cooler, but has a self contained cooling system that is powered through a 12 vdc cigar lighter plug. The system employs a small amount of ammonia and two small cooling fans. On start up it uses about 3 amps, then drops down a little after it has run awhile.
This system is not a refrigerator so there is no evaporator to freeze product, there's just cool air going in the box. It will only take the inside air down to 40 f below ambient, so if the air temperature in the galley is 80 f then the temperature in the box will be about 41 f, perfect for produce or juce. The price is really good at $100.
I have spent 4 days in reconstruction and installation, (I'm not a technician) I installed the cooler box in one piece and guess what; it works.
